Whales can cope with global warming better trees
Source:the Blue whale is one of the biggest animals in the world
There are many theories as to what will be the end of the world. Some scientists argue that life on Earth will disappear because of a meteorite, and the authors of the film with will Smith even showed us the death of people . However, the most likely outcome of our existence is the destruction from global warming. To prevent expected in 2050, the destruction of mankind, scientists are thinking to plant more trees which can absorb carbon dioxide and reduce the danger of the greenhouse effect. However, staff from that can provide 189 countries money to fight global warming, recently announced that instead of planting trees people ought to engage in protection and restoration of whale populations. But why do they think so?
According to the newspaper , Professor monetary Fund recently found out about the amazing ability of whales to absorb carbon dioxide. According to their calculations, each species of large whale species for their life duration is about 100 years old absorbs about 30 tons of carbon dioxide and neutralize it, even after death, settling on the bottom of the oceans. At the same time, one tree in one year your life will neutralize 22 kilograms of carbon dioxide, i.e. not more than 2.2 tons for a century. Comparing these figures it becomes clear that the whales can bring much important role in the fight against global warming .
How to avoid global warming?
Apart from the fact that the whales themselves absorb carbon dioxide, they saturate the area with water rich in nitrogen and iron waste. They are essential for the reproduction of the so-called phytoplankton — algae and microscopic creatures that also efficiently absorb carbon dioxide. According to one of the study's authors Ralph Chami, increasing the number of phytoplankton in the oceans, mankind can process several hundred tons of carbon dioxide. It is virtually the same as planting two billion trees. It is believed that in this scenario, each kit can make a contribution to the world economy in the amount of $ 2 million.
Why whales become extinct?
However, to achieve all of the above, people is extremely important to increase the population of whales. The fact that in the early twentieth century, these giants were open to mass hunting, which led to a substantial reduction in their number. At the moment, scientists account for about 1.3 million whales, whereas prior to the beginning of commercial hunting there were about 5 million individuals. Today, commercial whaling is prohibited, and their population is gradually recovering, but at the same time they continue to die for very different reasons.
Whales often beaching
Of Course, we are talking about environmental pollution. Today the seas and oceans literally , which enter the organisms of the inhabitants of the water and slowly poison them. Besides, there are many cases where aquatic mammals entangled in lost fishing nets and die due to the inability to move normally.
In the mortality of whales also guilty of noise pollution on our planet. The fact that produced by the ships sounds in the way whales hear and their relatives to navigate in space. Because of this, they often swim in the wrong direction and eventually jump ashore. Read more about the dangers of noise of cars, planes and ships can be found in .
